RAILROAD-SPIKE/ SPECIFICATION forming part of Letters Patent No. 462,045, dated October 27, 189 1.

Application filed May 6, 1891.

To all whom it may concern:

Be it known that I, DANIEL A. HEGARTY, a

citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful I1nprovement in Railroad and other Rail Spikes, which improvement is fully set forth in the following specification and accompanying drawing.

My invention consists of a spike provided with means for supporting the head of a rail, making the rail solid, and preventing shiftiu g thereof, as will be hereinafter set forth and definitely claimed.

The figure in the accompanying drawing represents a perspective view of a spike embodying my invention.

Referring to the drawing, A designates a spike, on one side of the head B of which is a depending pointed or sharpened tooth ,O, and on the opposite side thereof is a shoulder D. Rising from the shoulder D is an arm E, which extends from the'head in a direction obliquely toward the rail.

The spike is driven obliquely into the tie,

V the blows being struck upon the head B, and

Serial No. 391,845. No model.)

shifting of the head of the spike is prevented,v

and as the shoulder interlocks with the base of the rail and the head of the latter is sustained by the arm, as has been stated, the rail is held solidly and well adapted to sustain the strain to which it is subjected by carwheels on the gage side.

The spike and its connected parts are made in one piece, thus possessing strength and durability, and constructed of iron, steel, or other suitable metal, cast, wrought, forged, or otherwise produced.

Having thus described my invention, what Iolaini as new, and desire to secure by Letters Patent, is

1. A railroad-spike having a head with a brace-arm rising therefrom and a depending tooth on the side thereof, said arm being arranged obliquely to the rail, substantially as described. 7

2. A railroad-spike constructed with a head having a depending tooth to enter a tie, a shoulder to embrace the base of a rail, and an elevated brace-arm to engage the under side of the head of the rail and extending obliquely toward the said rail, said parts being combined substantially as described.
